Drilling deeper for dollars

Jul 1 - As oil consumption grows and access to most oil-rich regions becomes increasingly restricted, companies are venturing farther out to sea, drilling deeper than ever in their quest for energy.A decade ago when Chevron's Petronius came online it was one of the deepest water oil production facilities in the Gulf of Mexico --at 17-hundred feet. The next oil frontier - and the challenge for oil exploration - lies below 10,000 feet of water, through five miles of hard rock, thick salt and tightly packed sands. Ruben Ramirez reports.
